The HD Pentax DA 35mm F2.8 Macro Limited is an update to an older 'smc' design, with improved HD 'High Definition' lens coatings and a circular aperture diaphragm. It offers a 'normal' field of view (similar to a 50mm lens on full frame) in a compact, beautifully-constructed all-metal body with a built-in sliding hood. It's also a true macro lens offering 1:1 magnification at closest focus. The lens is available in either silver or black.
